@Clubdebambos
Some of these changes are being applied in the new mapping module implementation.

The reason this is occurring is because some properties (such as initial state) depend on a rendered map in the current implementation. The initial state is created on the Javascript side and not through the python side. We are working on changing this and relying more on python to initialize as much as we can.

Thanks for pointing out the time slider issue. I will test this on the new implementation and make sure the expected behavior is present

@Clubdebambos I've looked into this more and the time slider widget can only be created if the map is rendered either inside a jupyter notebook (in future a lab) or the GUI (i.e. map viewer).
This is because it is created with Javascript code and JS needs a browser to run. Any sort of widget will have this limitation since it is Javascript backend that we are calling.

We are working on a python implementation of the webmap but not of the individual widgets at this point so we don't plan on having this work without the map being rendered.

Initial state is part of the webmap definition so this will be handled in the new python implementation of the module.
